GAS-LAMP.

Specification of.' Letters Patent.

Patented Oct. 20, 1908.

Application filed October 15, 1903. Serial No. 177,096.

To all 'whom 'it may concern:

Be it known that I, GUsTAv RICHARD FICKERT, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Gas- Lamps, of which the following is a speciiication.

My invention relates to gas lamps, and

more particularly to burners for that char` acter of gas lamps employing incandescent materials.

It is a special object of my invention to provide a lamp which is particularly adapted for out-door use, as for street lighting purposes.

To this end the general objects in view are to provide a construction which is strong and robust and not apt to get out of order, and which, at the same time, may be easily and accurately adjusted. j

More specifically, the objects of the invention are to do away with the plug valve heretofore in universal use, and to provide in its place a valve mechanism which does not require lubrication and fine adjustment to prevent leakage, and which is not apt to be injured by rough usage; also to provide means for automatically cleaning the gas supply nozzle also to provide means whereby the supply of gas to the burner may be accurately adjusted, and the adjustment maintained; also to provide a pilot light mechanism which is economical in the use of gas, and reliable in operation.

rFliese, and other objects of my invention will more fully appear from the following description.

The invention consists in the novel parts, improvements and combinations herein shown and described.

The accompanying drawings, which are referred to herein and form a part hereof, illustrate one embodiment of my invention, and serve in connection with the description herein, to explain the principles thereof.

Of the drawings, Figure 1 is a side elevation of a burner for gas lamps constructed kin accordance with my invention; Fig. 2 is a vertical central section of the same taken on a plane parallel with the plane of Fig. 1; and Fig. 3 is a vertical central section taken on a plane at right angles with the plane of Fig. 2.

Like reference numerals refer to like parts.

ln accordance with my invention, means are provided for controlling the supply of gas to the nozzle of the burner, and means are provided for regulating the supply of gas through said nozzle, said regulating means being operated in unison with the controlling means.

ln accordance with the best embodiment of the invention, means are also provided for cleaning the nozzle of the burner, said cleaning means being also operated in connection with the controlling and regulating means.

In accordance with the best embodiment of my invention also, the controlling, regulating and cleaning means are combined in a single member, which member is preferably given a reciprocating movement. Some of the features of my invention, however, may be embodied in structures in which the elements are not so combined.

Referring to the particular construction illustrated in the drawings, 1 represents a suitable valve casing, said casing preferably being provided, as shown, with a substantially cylindrical valve chamber 2, which communicates at its lower end with a gas supply passage 3, and at its upper. end with a gas delivery passageformed in the nozzle 4 of the casing. So far as some of the features of my invention are concerned, any suitable form of valve may be used for controlling the supply of gas to the burner through the noz zle 4. ln accordance with the best embodiment of the invention, however, a reciproeating valve is used. The form of valve shown consists of a reciprocating member 5, which is mounted in suitable guides 6 and 7 in chamber 2 in alinement with the nozzle 4. As shown, the member 5 is provided with a conical portion 8, which is adapted to seat on a corresponding portion of the passage terminating in the nozzle 4 to cut off the supply of gas to the burner. Vihile this form of valve and seat is preferred, any other suitable form of valve and seat may be used, if desired. Above the valve portion S the member 5 is extended, and preferably provided with a pointed end 9, which is adapted, by occupying various positions in the opening through the nozzle, to regulatethe sup ply of gas therethrough.

In accordance with the particular embodiment of the invention illustrated, the member 5 is provided with a cylindrical portion 10 between the valve portion 8 and the pointed end 9, said cylindrical portion being made to closely fit the opening in the nozzle 4 so that when the member is moved up? wardly, the cylindrical portion 10 will pass through the opening and remove any .obstruction which may have become lodged therein. If desired, the cylindrical portion 10 may constitute, in addition to the cleaning means, the means for controlling the flow of gas to the burner, the valve portion 8, in that event, being dispensed with. Preferably, however, the valve 8 is used, in addition to the cylindrical portion 10, to for-m an extended surface which may be positively forced to its seat to prevent leakage. The passage forming a communication between the chamber 2 and the opening in the nozzle 9 is ypreferably made considerablyT larger than the portion of the member 5 located in said chamber, and the surface against which the valve portion 8 is adapted to seat .is preferably located. close to the mouth of the nozzle 4 in order that the full pressure of the gas may be exerted at the opening in the nozzle. While my invention as .to some of rits features is not limited to this particular construction, this is the construction employed in the best embodiment of the invention, for the reason that the maximum velocity of the gas issuing from the nozzle is insured, vthereby securing the most economical nimture of air and gas in the burner.

So far as some of the features of my invention are concerned, any suitable means may be employed for operating the member 5. In accordance with the best embodiment of the invention, however, the member 5 is reciprocated by an operating device having its movement positively fixed by means independent of the member 5. In accordance with the construction shown, the operating device for the member 5 consists of a shaft 11 journaled at one end in the casing 1, and at an intermediate poi-nt in a removable cover 12 for the chamber 2. Nithin the lchamber 2 the shaft 11 is provided with a pinion 13 adapted to mesh with suitable rack teeth cut in the member 5. At its outer end the shaft 11 is provided with an operating arm 14 which is confined between and positively limited in its movement by a pair of oppositely arranged stop lugs 15, 16 formed on the cover12. When the parts are assembled, the arm 14 is fixed on the shaft 11 in such a position that the arm comes in contact with the lug 15 yat the same time that the valve portion 8 of the member 5 comes in Contact with its seat. rihe lug 16 is provided with an adjusting device, as a screw 17, whereby the movement of the arm 14 in the downward direction may be adjusted so that the position of the pointed ,end of the member 5 in the opening of the nozzle 4 may be varied, as desired, to regulate the supply of gas to the burner. For the purpose of preventing leakage around the shaft 11, a stuffing box 18 is preferably provided. As shown, the nozzle 4 is arranged to deliver the gas into a suitable Bunsen tube 20, which is provided with a suitable burner nozzle 21 at its upper end. A supply of air through the lower end .of the tube 20 is controlled by a valve sleeve 22.

VIn accordance with the best embodiment of the invention, the lamp is provided with a suitable pilot vburner 23, which is supplied with gas by a tube 24 located within the Bunsen tube 20 and communicating with a suitable by-pass 2.5 in the casing 1. A needle valve 26 is preferably provided to regulate the flowof gas vthrough the -passage 25.

In ,accordance with my invention, the supplyof `gas to the pilot burner is controlled by a reciprocating valve member 27, which, as shown, is guided in a suitable recess formed in the `casing 1. As far as some of the features of my invention are concerned, any suitable means may be provided for reciprocating the valve member 27 in connection with the valve member 5 in such a manner that when gas is admitted to the main burner it will be .cut off from the pilot burner, and vice versa. As shown, the valve member 27 is provided at its upper end with a cylindrical valve portion 28 adapted, in its upper movement, to enter the lower end of the bypass 25, and thus cut off the supply of gas to the pilot burner, and said member is provided lwith rack-teeth adapted to mesh with the pinion 13 on the opposite side thereof from the member 5 in such a manner that when the member 5 is moved upwardly to cut off the supply `of gas to the main burner, the member 27 is moved downwardly to admit gas to the pilot burner. The guide passage for the member 27 is preferably extended to the lower end of the casing 2, and is closed by a removable screw 29 in such a manner that by removing the screw 29 the member 27 may be removed from the casing. The o eration of the device having been fully described in connection with the description of the construction thereof, further description of the operation will be unnecessary.

My invention, in its broader aspects, Vis not limited to the precise construction shown and described, nor to the particular construction by which it may be carried into effect, as many changes may be made in the construction without departing from the main principles of the invention, and without sacrificing its chief advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is A:--
